The Scubapro Donut Wing Single Tank Configuration is a technical backplate-and-wing air cell, originally sold as the X-TEK Donut Wing and continued today by SCUBAPRO under its S-TEK line, built for divers running a single tank on a backplate and harness rig.

Compatibility and sizing
This wing is built to pair with SCUBAPRO S-Tek and X-Tek backplates and harnesses, and SCUBAPRO confirms older X-TEK hardware remains compatible with the newer S-TEK parts, so divers upgrading from an X-TEK setup can keep using existing backplates and harnesses.
